Are genes our destiny or just our potential? How might genetic variations affect our nutrient status and predisposition for issues as complex as obesity and hypertension or as simple as caffeine sensitivity? Join dietitian Mary Purdy as she discusses her insights and experience working with clients utilizing Nutrigenetics like SNP's (single genetic variants) as well as POLYGENIC PROFILES in conjunction with blood labs and symptom assessment to help personalize assessment and recommendations.


Selected Questions:

Can I have my nutrigenomics tested? Is it covered by insurance? Do you know what the policy is with insurance carriers? If not, what would the "out of pocket" expenses be?

Can the consumption of specific foods alter gene expression?

Do specific nutrients directly cause disease (for example, high cholesterol equals stroke; high caffeine equals heart palpitations)?

Does the consumption of animal protein cause DNA defects leading to cancer?

I've heard that dairy consumption can be harmful, particularly casein. Would the study of nutrigenomics determine this?

In 2015, a meta-analysis of 38 genes found no association between dietary intake and disease. Has more recent research been conducted to prove otherwise?

Is the "eat everything in moderation" approach practical anymore, or are there actual foods that are considered harmful to your health?

Is there a good standard reference to use for recommended labs and assessment? I am particularly interested in MTHFR (c677t)

Is there a relationship between my gut microbiome and my nutrigenomic profile?

It seems nutrigenomic tests are costly tools used to identify disease. Obtaining biomarkers and hormone levels are also costly. Are these techniques applied in day to day clinical practice by RDNs, LDNs or physicians?

What are the best resources and training available to dietitians who want to become experts in this area?

What companies offer the best nutrigenomics tests for use in practice, and what research do they have to support their testing?
